Homophone search Leave feedback

Homophone search, or in other words phonic search, allows you to find not only the words specified in the search query, but also the homophones, words that are pronounced the same but differ in meaning.

To enable homophone search, you must set the UseHomophoneSearch property of the SearchOptions class to true. By default, homophone search is disabled.

The default homophone dictionary contains homophones only for the English language. To manage the homophone dictionary, see the Homophone dictionary page in the Managing dictionaries section.

The following example demonstrates the homophone search.

C#

string indexFolder = @"c:\MyIndex\";
string documentsFolder = @"c:\MyDocuments\";
 
// Creating an index in the specified folder
Index index = new Index(indexFolder);
 
// Indexing documents from the specified folder
index.Add(documentsFolder);
 
// Creating a search options object
SearchOptions options = new SearchOptions();
options.UseHomophoneSearch = true; // Enabling homophone search
 
// Search for the word 'coal'
// In addition to the word 'coal', the words 'cole' and 'kohl' will also be found
SearchResult result = index.Search("coal", options);
